# Monitoring change history

## Overview

**Change history** is a tab in the Monitoring section of a cost management group in Cost Analyzer. It lists the configuration changes that users made to the group's group budget, anomaly detection, custom monitors, and Budget planner, newest first. Each entry shows what changed, who changed it, and when, and you can open the entry to compare the old and new settings.

The Monitoring tab strip reads **Overview**, **Group budget**, **Anomaly detection**, **Custom monitors**, **Budget planner**, **Incidents**, and **Change history**. **Change history** is the last tab.

### Business value

Monitoring settings decide when your team is alerted about Azure spend. When an alert stops firing or starts firing too often, the first question is usually what changed. Change history answers it in one place, so you can audit who changed a budget, an anomaly configuration, or a monitor without searching through general activity logs.

## Prerequisites

You need access to the Monitoring tab of the cost management group whose changes you want to review.

### Required permissions

Change history has no permission of its own. It appears whenever the Monitoring tab appears, and the entries you see depend on your Read permissions for the four monitoring sources.

| Role | Permission | Access |
| --- | --- | --- |
| Account owner, Owner, Contributor, Reader | Not applicable | View entries from all four sources |
| Custom role | **Group budget**: Read | View **Group budget** entries |
| Custom role | **Anomaly detection**: Read | View **Anomaly detection** entries |
| Custom role | **Custom monitors**: Read | View **Custom monitors** entries |
| Custom role | **Budget planner**: Read | View **Budget planner** entries |

When you assign a custom role, enable **Monitoring** under **Specify feature permissions**. Then turn on Read for each source under **Specify monitoring tab permissions**. Manage permission is not required to view Change history.

## How it works

Change history is a read-only view of the user activity that Cost Analyzer records for the group's Monitoring section. It shows changes for the selected cost management group only. Changes made to its subgroups are not included.

Entries are grouped by day by default. Each day header reads **Today**, **Yesterday**, or the date, followed by the number of changes, for example "2 changes". Each entry has a description such as "Updated - Monitor settings for group budget monitor in Cost Management Group Contoso", the user who made the change, a relative time, a timestamp, and a **Details** link.

Cost Analyzer records the following changes:

- **Group budget:** adding a group budget monitor and updating its settings.
- **Anomaly detection:** the first configuration of automatic anomaly detection and later updates to it.
- **Custom monitors:** adding, updating, and removing a monitor, enabling or disabling monitoring, and changing a monitor's name or description.
- **Budget planner:** saving the budget planning configuration.

Click **Details** to open the **User activity details** blade, which has the **Summary**, **JSON**, and **Changes** tabs. The **Changes** tab compares the old and new values and appears for entries that recorded the previous settings. Use **Expand view** on the **Changes** tab to open a larger comparison.

The source tabs and the **Group by** list appear after the first load completes. The source tabs show **All** plus the sources you have Read permission for. Entries from a source you cannot read are hidden, including under **All**. The list loads 50 entries at a time, and **Load more** fetches the next 50.

              
              

Change history shows the last 30 days of changes. Older changes are not available.

## Steps

Use these steps to review, filter, and export the changes recorded for a cost management group. Open **Cost Analyzer**, select the cost management group, and select the **Monitoring** tab to get started.

### Review changes

Reviewing changes shows who changed the monitoring configuration of the group and when.

1. Select the **Change history** tab, the last tab in the Monitoring tab strip.
2. Select a source tab such as **Group budget** to show only the changes from that source, or stay on **All**.
3. Review the entries under each day header.
4. Click **Load more** at the end of the list to fetch older entries.

### Filter changes

Filtering narrows the list to a source, a period, or specific users.

1. Open the **Group by** list and select **Day** or **User** to change how entries are grouped.
2. Click **Date** and select **24 hours**, **7 days**, or **30 days**. The preset applies immediately. Alternatively, select **Select custom date**, choose the **From** and **To** dates, and click **Apply**.
3. Click **User**, search for a user, and select one or more users.
4. Click **Clear** in the **Date** or **User** filter to reset it.

### View the details of a change

Viewing the details shows exactly which settings changed.

1. Click **Details** on an entry to open the **User activity details** blade.
2. Review the **Summary** tab for the activity, the user, and the time.
3. Open the **JSON** tab to see the recorded details, or open the **Changes** tab to compare the old and new values.
4. Click **Expand view** on the **Changes** tab to open a larger comparison.

### Export and refresh the list

Exporting gives you an offline record of the entries you are viewing, and refreshing reloads the list.

1. Click **Export logs** at the top right to download an Excel file of the entries currently visible. The file has the columns **Activity type**, **Description**, **Performed by**, **Detail**, **Category type**, **Feature type**, and **Logged At**.
2. Click the refresh button next to **Export logs** to reload the list. The refresh button also resets the **Date** and **User** filters.

## Configuration

The Change history filters apply only while you view the tab. Cost Analyzer does not save them.

| Option | Default | Description |
| --- | --- | --- |
| Source tabs | All | Shows entries from one source. The options are **All**, **Group budget**, **Anomaly detection**, **Custom monitors**, and **Budget planner**. Only the sources you can read are listed. |
| Group by | Day | Groups entries by **Day** or by **User**. |
| Date | No date filter | Limits entries to **24 hours**, **7 days**, **30 days**, or a custom range. The custom **From** and **To** dates must fall within the last 30 days, and **From** must be earlier than **To**. |
| User | All users | Limits entries to the users you select. |

## Permission behavior

What you see in Change history depends on your Read permissions for the four monitoring sources.

| Access level | What the user can do |
| --- | --- |
| Read on all four sources | View entries from **Group budget**, **Anomaly detection**, **Custom monitors**, and **Budget planner**, and export them |
| Read on some sources | View and export only the entries from those sources. The other sources are not listed as tabs and are hidden under **All**. |
| No Read on any source | The Monitoring tab and Change history are not shown |

Change history has no Manage actions. **Export logs** is available to everyone who can open the tab, and it exports only the entries you can see.

## Example scenario

A FinOps lead has Read permission for **Group budget** and **Anomaly detection**, but not for **Custom monitors** or **Budget planner**. The lead opens the `Retail-Prod` cost management group, selects **Monitoring**, and then selects **Change history**.

The source tabs show **All**, **Group budget**, and **Anomaly detection**. Under **Today**, the lead sees "Updated - Monitor settings for group budget monitor in Cost Management Group Retail-Prod" made by a colleague. Under **Yesterday**, the lead sees "Updated - Automatic anomaly detection configuration for Cost Management Group Retail-Prod". Changes to custom monitors and Budget planner in the same period are not listed, not even under **All**.

The lead clicks **Details** on the group budget entry and opens the **Changes** tab to compare the old and new monitor settings. The lead then selects **7 days** in the **Date** filter, changes **Group by** to **User**, and clicks **Export logs** to keep a record of the entries on screen.

## Limitations

- Change history shows the selected cost management group only. It does not include changes made to its subgroups.
- Change history shows the last 30 days of changes, so you cannot review older changes.
- Changes made through the exposed API and incident status changes are not recorded. See [Managing monitoring incidents](https://docs.turbo360.com/docs/managing-monitoring-incidents) for the incident history of an alert.
- Changes to Reservation and Savings plan monitors are not shown here. Review them in [Cost Analyzer user activities](https://docs.turbo360.com/docs/cost-analyzer-user-activities).
- Older entries may appear only under **All**.
- You cannot filter the list to a single monitor. Use the **Custom monitors** source tab and read the entry descriptions, which include the monitor name.
- Change history is read-only. You cannot undo or restore a previous setting from it.

## Troubleshooting

1. **The Change history tab is not visible** Cause: Change history appears only when the Monitoring tab appears. Your role has no Read permission for **Group budget**, **Anomaly detection**, **Custom monitors**, or **Budget planner** on this group. Fix: Ask your administrator to enable **Monitoring** and turn on Read for at least one row under **Specify monitoring tab permissions** in your role.
2. **A source tab, such as Budget planner, is missing from Change history** Cause: You do not have Read permission for that source, so Cost Analyzer hides its tab and its entries. Fix: Ask your administrator to turn on Read for that row under **Specify monitoring tab permissions** in your role.
3. **The list shows "No user activities found"** Cause: No changes were recorded in the selected period, the changes are older than 30 days, or the selected source has no entries you can see. Fix: Select **All**, widen the **Date** filter, clear the **User** filter, and confirm that your role has Read permission for the source you expect.
4. **A change you made is missing, although it is within 30 days** Cause: The change was made through the exposed API, it was an incident status change, or it was made in a subgroup. These changes do not appear in the selected group's Change history. Fix: Open the Monitoring tab of the group where you made the change, or review incident actions from the **Incidents** tab.
5. **The Apply button in the Date filter is disabled** Cause: The custom **From** date is later than the **To** date. Fix: Correct the dates, or select a preset such as **7 days**.

## FAQs

1. **How far back can I review changes?** You can review up to 30 days. Change history does not keep older changes, and the custom **From** and **To** dates are limited to the last 30 days.
2. **Does Change history show changes made to subgroups?** No. It shows the changes recorded for the selected cost management group only. Select the subgroup to review its own changes.
3. **Does exporting or viewing Change history create an entry?** No. Viewing, filtering, and exporting do not create entries. **Export logs** exports only the entries currently visible to you.
